PreSonus diversified their product lineup in several directions at Winter NAMM 2013. A great example of the new directions is the Eris monitors. The Eris Series are 2-way, bi-amped monitors designed to deliver accurate response with tight low end and transparent top end. Back-panel controls allow adjusting the monitors to match the acoustic listening environment. There are two models: the Eris E8 has an 8-inch Kevlar woofer driven by 75 watts of power, a 1.25-inch silk-dome tweeter driven by 65 watts of power, and frequency response from 45Hz to 22kHz. The Eris E5 has an 5.25-inch Kevlar woofer powered by 45 watts, a 1-inch silk-dome tweeter driven by 35 watts, and frequency response from 64Hz to 22kHz. Both models have balanced XLR and 1/4-inch inputs, and unbalanced RCA inputs.
